METAL WEATHER-STRIP.

Specification of Letters Patent.

Patented J une 28, 19M).

To all whom t may concern:

Be it known that I, PETER L. I-IEDBERG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Metal leather-Strips, ofwhich the following is a specification.

This invention relates to improvements in metal weather strips, whichare more particularly adapted for use on window frames and in the guideways for the sashes thereof, yet are applicable also for door frames,and it consists in certain peculiarities of the construction, novelarrangement and operation of the parts thereof, as will be hereinaftermore fully set forth andV specifically claimed.

The main object of the invention is to provide weather strips which areprincipally designed to be secured to the uprights of the window frames,and extended into the guide ways for the sashes thereof, and which shallbe of such constri'ictioi'i as to prevent the passage of air, dust,rain, snow and moisture between the parts of the window frame andsashes, as well as to co-act with the sashes or other elements withinthe frame in such a manner as to prevent rattling, and to compensate forany inequalities due to warpage or shrinkage.

Another object of the invention is to provide a weather strip which maybe applied to the top or bottom of the frame in such a manner as toprevent the passage of air, rain and moisture between the upper andlower rails of the sash frames.

Various other objects and advantages of the invention will be disclosedin the subjoined description and explanation.

In order to enable others skilled in the art to which my inventionpertains, to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1, is ahorizontal sectional view of a portion of a window frame, and a part ofthe sashes thereof showing them equipped with metallic weather stripsembodying one4 form of the invention. Fig. 2, is a detached perspectiveview of apart of one of the weather' strips employed in the constructionillustrated in Fig. 1. Fig. 3, is a view partly in cross section andpartly in elevation of the lower portionl of the window frame showing amodification in the construction of the weather strip as applied to thewindow sill. Fig. 4, is a detached perspective view of a portion of thestrip of the construction shown in Fig. 3. Fig. 5, is a horizontalsectional view of a portion of a window frame and a part of one of thesashes thereof, illustrating another modified form of the weather stripmounted thereon. Fig. 6, is a detached perspective View of a part of thestrip of the construction shown in Fig. 5.

Like numerals of reference, refer to the corresponding parts throughoutthe different views of the drawing.

The reference numeral 10, designates a portion of one of the uprights orside pieces of a window frame which may be provided as usual with aparting-stop 11, an inside stop 12, and an outside stop 13, which stopsprovide guide ways for the side stiles 14, of the sashes.

Referring now, to Figs. 1, and 2, of the drawing, the reference numeral15, designates one of the strips as a whole, which is secured to thewindow frame 10, by means of the parting-stop 11, which is inserted in avertically extended mortise 16, as is clearly shown in Fig. 1, of thedrawing.

Each of the weather strips 15, consists of a strip of metal possessingsome resiliency and formed angular-ly in cross section, that is to say,is provided with two flanges 17, and 18, the former of which will betermed the mortise flange, and the latter the guide way flange. As shownin Figs. 1, and 2, the mortise flange 17, is extended into the mortise16, at one of the sides thereof, and is held in place by theparting-stop 11, in such a manner that the guide way flange 18, will lieagainst the inner surface of one of the guide ways of the upright 10, ofthe window frame. The mortise 16, is preferably formed at the inner edgeof each of its sides with an enlargement 19, to receive a deflectedportion 20, on the free edge of the flange 17, thus providing means formore securely holding the strip in position when the parting-stop 11, isinserted in its mortise. As is clearly shown in Fig. 2, the guide wayfiange 18, is provided with a leaf 21, bent approximately back upon thefiange 18, which leaf has an extension 22, integral therewith, andinterposed between the flange 18, and leaf 21, and normally at anglesthereto. As the strip is composed of resilie'nt inaterial, it isapparent that the parts before the sash frames are placed in position,in the window frame, will assume the positions shown in Fig. 2, of thedrawing, but when pressed by the side rails ofthe sashes, the parts willlie in parallelism or substantially so, one with the other, as is shownin Fig. 1, of the drawing.

By constructing the weather strip as above described, it is apparentthat one may be placed on each side of the inortise 16, and that theparting-stop 11, will firmly hold them in position without the use ofspikes or other securing devices, and that the resiliency of thematerial will cause the flanges 18, and leaves 21, to rest closelyagainst the surface of the guide Ways in the uprights 10, and againstthe adjacent surface of the sash stiles 14, respectively, and in such amanner as to absolutely exclude the passage of air, and to prevent thesashes rattling.

In Figs. 3, and 1, of the drawing, is shown a modification in theconstruction of the weather strips which is more especially adapted tobe applied at the bottom and top of the window frame and it consists inemploying a strip which is indicated as a whole, by the referencecharacter 15a, which consists of a strip or piece of metal possessingsome resiliency and formed angular in cross section, that is to say,with a narrow flange 17, to fit under the inner edge of the stool 23,ofthe window frame, and with a wider flange 1S, to lie verticallyagainst the inner surface of said stool. In this modified constructionthe flange 17, corresponds with the mortise flange 17, of the firstdescribed construction, except that it is much narrower, and is notprovided with a deflected portion Q0, while the flange 18a, correspondswith the flange 18, of the first described construction, and like thesaine is provided with a leaf 21a, having an extension 22, integraltherewith, and interposed between the flange 18a, and lead 21a, andangular thereto. Secured to the upper surface of the window sill 24,near the inner portion of the stool 23, is a metal strip or base piece25, which has an upturned flange 26, interposed between the flange 18a,the leaf 21a, and the free edge of the extension 22,

thereof, which will give additional strength or rigidity to the strip15a, as is apparent.

In Figs. 5, and 6, is shown still another modification in theconstruction of the weather strip, which is designed to be applied toeither the uprights of the window frame and side stiles of the windowsashes, 01 to the sill, which consists of a strip of metal designated asa whole, by the reference character 15b, which is bent angularly incross section, that is to say, to form a flange 17D, to rest against andbe secured to the inner portion of one of the sides of the parting-stop11, and the flange 18, to lie against the surface of one of the guideways of the upright 10, of the window frame. rlhe flange 18D, isprovided with a leaf 2lb, which is integral therewith, and bentapproximately back upon the same, yet normally has its free edge at aslight distance therefrom, thus affording a resilient leaf 2lb, to restagainst the outer surface of one of the side rails 141, of the windowsash. Secured to the parting-stop of the window frame, is a strip ofmetal 25a, which is provided with a flange 26a, at an angle thereto, andis interposed between the leaf 2lb, and the flange 1S", which willstrengthen the strip 15, and firmly hold it in place.

Having thus fully described my invention, what I claim as new and desireto secure by Letters-Patent is- The combination with a window-framehaving the usual parting stops, of a piece of metal having a flangesecured longitudinally in the groove in which the parting stop is fittedand provided with another flange at an angle to the first-named flangeand lying longitudinally against the inner surface of the guide way forthe window sash, the last-named flange having a leaf integral therewithand extended approximately back thereon toward the parting stop, and anextension on said leaf interposed between the leaf and the secondnamedflange and normally at an angle to the same.
